OTN article: Speedy Perception trumps Speed Reception – on Smart Asynchronous Interactions in multi layered architectures

Lucas Jellema

The Oracle Technology Network has just published my article on asynchronous interactions used in multi-layered architectures to free up resources and create at least the perception of speedy processing. This article describes how, by leveraging opportunities for asynchronous processing, at least the perceived responsiveness of our systems is likely to improve. Frequently, the actual scalability is also enhanced by making much better use of the parallel processing power of today’s CPUs and virtual machines and through throttling peak loads by deferring some of the work. Many examples are presented of various key mechanisms at each of three layers – browser, middle tier/middleware and database – that enable such asynchronous interactions.
